Select object with the given id (__oid) then render it. If the
object isn’t selectable, try to select fallback object if
__fallback_oid is specified.

If specified initargs is expected to be a dictionary containing
arguments that should be given to selection (hence to object’s __init__
as well), but not to render(). Other arbitrary keyword arguments will be
given to selection and to render(), and so should be handled by
object’s call or cell_call method..
